[ net tr y e ] = train(net,x,t);
Obtain trnind, valind and tstind from tr. To see how to do this, just
type, without the ending semicolon,
tr = tr
Hope this helps,
Greg
Thank you for formally accepting my answer

Reread my instructions:
The trn/val/tst indices are in the training record tr. Therefore, use the command
tr = tr
and the rest will follow!

Thank you I got it. However how can I determine the standard deviation of inputs or outputs? std(tainInd) doest not work. Please suggest.
